Well....the excuse could be the dishes are grounded/bonded/whatever.
Interesting construction.....you don't see row-houses like that (and that clean) in da big city here. Dig the numbers on the street too.
In all seriusness, is there a chance that water can leak through the holes that contain the bolts holding the antenna to the meter pan?
What if one of those screws hit a live conductor in there? God help the person who goes ahead to try and re-align the dish after it's been knocked out of position by a runaway basketball.
Betcha the guy used sheet metal screws.....
